My guess is that the hairs are far apart and either grow slowly or do not grow "regularly."

When I don't shave for a month, I have a pretty rubbish beard. Therefore I too shave so as not to look ridiculous.

Early Christian Rubbish Beards: While he is a giant and a firebrand, St. John Chrysostom had a pretty pathetic "beard" compared to his contemporaries (and certainly compared to the Cappadocians). Assuming he kept the monastic practices all his life, what we see of his beard in iconography is as good as it gets.

I could have sworn that last time you mentioned Russell Brand and I looked him up, he was some kind of businessman. Now, according to Wikipedia, he is and always has been a comedian. What's up with that?
